re: origin of pterosaur eggs

Hi Evan,

You bring new light to the argument. Thank you. I was not aware of embryonic 
diapause.

A short article describing the anurognathid with egg-cracking teeth (not an 
ornithocheirid embryo) in the egg shell is coming out this month. Similar wing 
phalanx proportions probably caused the error.

For now, at least, there are no pterosaur eggs. Still wondering, though, about 
Chiappe's find.

Best,

David Peters
